Marisa Jeffrey O’Sullivan Named One of Dallas’ 2020 Best Lawyers Under 40

Congratulations to Marisa Jeffrey O’Sulllivan, who was recently named one of D Magazine’s Best Lawyers Under 40.

This is the second year Marisa has been recognized by D Magazine, and it’s the latest in a series of accolades for this outstanding young lawyer. She has also twice been named to the Rising Stars list published by Super Lawyers (Thomson Reuters), and she received the 2019 Outstanding Young Lawyer Award from the Dallas Association of Young Lawyers.

“We are immensely proud of Marisa,” said firm founder and managing principal Amy Elizabeth Stewart. “She is an invaluable member of our team and a leader in the Dallas legal community. It’s no wonder she’s consistently acknowledged by her peers as an exceptional lawyer.”

In addition to her exemplary work on behalf of firm clients, Marisa also serves on the board of directors of both the Dallas Women Lawyers Association and the Dallas Association of Young Lawyers. She has published several articles on insurance law and presented to both in-house counsel and bar organizations on various insurance and litigation topics, including cyber insurance, e-discovery, and the tripartite relationship.

To compile the list of honorees, D Magazine asked lawyers to nominate Dallas lawyers under 40 whose work they have witnessed firsthand. From the list of nominees, an anonymous panel of attorneys selected the final winners.
